" To all whom'it may concern:

- Be it k nown that LOARL'KNOP a subject of the king-of Prussia, German Emperor, and a resldent of Hemelingen, near Bremen,

in the Empire of Germany, have invented a.

new and useful apparatus for use in processes forobtammg pure cotton or fibrous material suitable for textile and like pur oses from as, for-exam le,- the cotton-seed 1 ulls of oil, factories an for use in'processes for obtaininfi ginning-works or other indus-.

' trial waste containing fibrous materials-apparatus according to the resent invention euig-particularly intende for use in carrya ing out the processdescribed in the specificaapplication, Seria N o': 266,069, date Junetion accompanyin the'Unit'ed States atent 19, 1905, and comprisesrwashing and hulling apparatus which serves for completely sepa--' rating the hull remainsiand other impurities from the fibers.- As a rule, in the'case of manufacturing processes employed'up to the present time a not 'inconsi I erable, quantity of cotton has remained adhering to the cotton-seed hulls. 'As these remnants are only used as fodder for cattle, the said quantity of cotton is completely lost as far as the textile 35. ture re erred to make 1t possible to separate industr isconcerned;v Processcs'of the na- 'out in an industrially applicable pure form these remnants of cotton, as, well as the fibrous rerrmants of other waste material from works, which material may be incrusted and soiled by dirt or eolo.ring-niatter-for; exam- I Ie, the waste products of the industries dealmg with the treatment of jute. and other fibrous materials. I 1

,Accordin to the processes of'the nature described t no waste inaterials ofthe'above .nature are first treated in-suitable see'thers or like vessels with solutions of chemicals WhlG'h are able to dissolve both the impurities of the fibers and of the hull remains, but which, however, attack the fibers themselves only to a trifling extent .or absolutely not at al the apparatus from one end to Specification of Letters seam. Patented March 1s,1eoe. A emia filed 1 19,1905. semi No. 260,070,

Chemicals suited for this pur ose are, among.

others, the well-known a alies, alkaline earths, diluted acids, alkaline sulfites, calcium sulfite, sodium bisulfite, &c. T e-wasteissior: HEMELINGEN,

l v vbisulfite, magnesium bisulfite, ota'ssnuabis multaneously treated in the Vessel with one or more of these solutions until the hulls, etc, are disintegrated entirely or for the greater "part withoutthe fibrous material itself being attacked in .a noticeable manner.

fibrous mass is then The laced in washing and hulling apparatus w ich serves forcompletely separatin the hull remains and other impurities from t e fibers.

Apparatus according to the present invention. is illustrated by way-oi example in the accompanying drawin s, in which:'

Figure, 1 is a central vertical section, and

Fig. 2 is a cross-section, of the scooping device forming part of the apparatus.

Upon the shafts, which may pass through which'isdriven in a suitable manner, a numeach 'with a scooping device. These scooping devices may suitably con'sist of one, two, 1

or more tubes s, bent knee-she ed, which on the shaft a being rotated dip into the hull e other and v ber of conical sieves b b "are arranged, said sieves being provided at their narrower and ingvats d d,st anding under said shaft, and simultaneously scoop a portion ofthe fibrous mass in said vats into the rotating sieves b b; In each hulling-vat a conical device which is open'belowds situated, said device bein provided in itslower part with a number n vertical ribs. -or edges f. The worms or screws'k, arranged on vertical shafts i in the lower artof the devicesaare driven from a secon shaft 9 by means of-beveiwheels h' or in any other'suitable manner, narrow wlngs. i

through the sieves.

IUnder the 0011- tended to disintegrate or loosen the hullremains-flows with the solution withwhich itisy mixed into-the device e of the vat d.

The re mains of the hulls, &c., arecontinu'aily more:

' from the adhering water by means of means of the'cooperation of the mixing-" screws k and the ri s f and by means of the beaters'l, the solvent being besides washed out with water. By means'of the scoops cof the conical'sieve b the mass then raised into the latter, and. the fibers subsequently arrive in the second vat (1, while the rinsingwater flows away into the dish m, situated under the sieve b. In said vat a! the fibrous mass is treated with fresh. water in the same. manner as previously it was treated in the vat d until it passes by means of the scooping device into the second sieve d and thence into the third vat, (not shown,) and so on until the fibrons mass is freed com letely from the adhering hull remains and chemicals. Pure water is suitably contained in the first vat d for washing out and diluting the li uid' with which the material has been boi ed, whereas suitable additions .are advantageously made to the rinsing-water in the subsequent vats for the purpose of bleaching the fibrous mass until the fibrous massis finallyrinsed out in pure water.

The number of wash-vats and sieves, vary as desired, according to the nature of'th material to be worked u and s rayingde;

vices and nozzles or the 11 e may e provided,

and arranged as desired, according to requir ments, in the sieves for the purpose ofaidin in their action. I 1

- The pure cotton or other veget'a won in the described manner is to'lfbeyfreed' trifugal apparatus or draining-rollers and to.b,e completely dried, whereuponsaid terial is loosened in carding rnachines, the,

short and long fibers being separated-from one another. l
